  • Optimization of the cushion properties of Amphibious Aircraft landing gear by simulation and drop test
    Journal of Vibration and Control, 2012
    Co-Authors: Caijun Xue, Wang Yue, Bin Sun

    Abstract:

    This paper proposes a method of optimizing the cushion properties for a certain Amphibious Aircraft landing gear, which is establishing an accurate simulation model in least mean square by adjusting parameters. First, carry out a drop test under initial parameters to get the friction between the tire and platform, and the elastic parameters of the wheel to simulate the interactions of components. Second, repeatedly modify the model by analyzing the results of comparisons between the drop test and simulation until an accurate model with optimal parameters is established. Finally, verify that the cushion properties of the landing gear with the optimal parameters meet the requirements of airworthiness rules and the properties are greatly improved. The study shows that an adjusting-parameter drop test for establishing a simulation model is an available and reliable way to optimize the cushion properties of an Amphibious Aircraft landing gear.

  • survey on the novel hybrid aquatic aerial Amphibious Aircraft aquatic unmanned aerial vehicle aquauav
    Progress in Aerospace Sciences, 2015
    Co-Authors: Xingbang Yang, Tianmiao Wang, Jianhong Liang, Guocai Yao, Miao Liu

    Abstract:

    Abstract The aquatic unmanned aerial vehicle (AquaUAV), a kind of vehicle that can operate both in the air and the water, has been regarded as a new breakthrough to broaden the application scenario of UAV. Wide application prospects in military and civil field are more than bright, therefore many institutions have focused on the development of such a vehicle. However, due to the significant difference of the physical properties between the air and the water, it is rather difficult to design a fully-featured AquaUAV. Until now, majority of partially-featured AquaUAVs have been developed and used to verify the feasibility of an aquatic–aerial vehicle. In the present work, we classify the current partially-featured AquaUAV into three categories from the scope of the whole UAV field, i.e., the seaplane UAV, the submarine-launched UAV, and the submersible UAV. Then the recent advancements and common characteristics of the three kinds of AquaUAVs are reviewed in detail respectively. Then the applications of bionics in the design of AquaUAV, the transition mode between the air and the water, the morphing wing structure for air–water adaptation, and the power source and the propulsion type are summarized and discussed. The tradeoff analyses for different transition methods between the air and the water are presented. Furthermore, it indicates that applying the bionics into the design and development of the AquaUAV will be essential and significant. Finally, the significant technical challenges for the AquaUAV to change from a conception to a practical prototype are indicated.
